. 4 Application filed ma -2.1906. Serial No. 314,775.

Be it known that I, LEON FEVAL, a citizen of the Republic of France, residing at Newark, in the county of Essex and State of New Jersey, have invented a certain new and useful Process of Producin a Dull Finish on Coated Leather, of whic the following'is' a description.

.The object-I have in view is an improved process for treating coated, sized, or japanned eather so that the otherwise gloss and Thepreferred application of the invention is in connection 'w;1t leather treated with yclosed in my copendin'g a lication forpatent, Serial No. 314,773, l il dd May2, 1906. The invention, however, is not necessarily limited to use in connection with pyroxylincoated leather, as it may be usedinconnection with leathers which are coated by ordi- T he preferred way of carrying out my proc'-. ess is to press a sheet of paper against the bright-fimshed surface. A dull finish will thereby be obtained, which can be regulated wil produce a surface having a duller finish than paper containing a larger proportion of means of the dies or plates used for obtaining the grained or pebbled surface on the leather.

Any form of apparatus may be used for' Figure '1 represents a'diagrammatic-al construction of an apparatus-employing rollers, and'Fig. '2 a similar view of an apparatus emp10 -ing plates.

In Fig-1, m a represent rollers through which the finished leather 6 is passed. c is a sed'between the finished ace'of the eather and one of the rollers. These rollers may have polished a this 24th'day of April, 1906. LEON- FEVAL.

grain or pebble the leather to the desired extent. e

In Fig. 2 instead of the rollers a a plates d d are used and the finished leather 6 and paper 0, as before described, are interposed bfe' tween the two.

The thickness of the paper is immaterial,

except that when the rollers or plates have embossed surfaces a thin paper is more de-.

sirable, as it will more readily assume the form and details of the embossin The rollers or plates 'used may be heate' .at ordinary temperatures; but a temperature of from 150.Fahrenheit to 200 Fahrenheit is found to give the most perfect results, particularly on a leather'coated with a pyroxylin compound. The rollers and plates may be heated in any manner, the coil e withinfthe rollers a a or'plates-d (1 being shown for pur oses of illustration. It is to be understood t at the surfaces, or they may be embossed so as to paper will absorb part of the oil from the coating of theleathenand to this extent will" render the. finish duller.- It is therefore ad-T visable not toattempt to use one sheet of paper for more than one application'in order to secure the most perfect results.
